Invoke BSP Editor GUI
  • For Quartus® Prime Pro Edition software, use qsys-edit --1=.bsp.
  • For Quartus® Prime Standard Edition software, use niosv-bsp-editor .
  • For Quartus® Prime Pro Edition software, use nios2-bsp-editor or qsys-edit --1=.bsp.
    Note: The BSP Editor is integrated into Platform Designer.
  • For Quartus® Prime Standard Edition, use nios2-bsp-edit.
    Note: The BSP Editor is not integrated as part of Platform Designer.
Invoke Command Shell niosv-shell
  • In the Windows operating system, on the Start menu, point to Programs > Intel FPGA > Nios II EDS <version>,and click Nios II <version> Command Shell :.
  • In the Linux operating system, in a command shell, change directories to <Nios II EDS install path>, and type the command nios2_command_shell.sh.
Create a BSP niosv-bsp -c –p=<path to .qpf file> -s=<path to .qsys file> -t=<bsp type> [OPTIONS] settings.bsp nios2-bsp <bsp type> <bsp-dir> [<sopc>] [<override>]
Generate a BSP niosv-bsp –g [OPTIONS] settings.bsp
Update a BSP niosv-bsp –u [OPTIONS] settings.bsp
Examine a BSP niosv-bsp –q –E=<script name> [OPTIONS] settings.bsp nios2-bsp-query-settings --settings settings.bsp
